Cockpit Drains

[Yogomana]

Hi

On Yogamada a Mk1 there are two small drains at the level of the cockpit floor. They are the standard 12mm holes with a thread for bungs (that need to be in when underway as water flows in alarming the crew)

This is inadequate for dealing with even a mild pooping and I am planning to fit some 30mm drains with non-return valves.

Has anyone dealt with this issue or got any advice before I get happy with the power tools?

Thanks in advance and feel free to email me off post; redston (at) bushtech.com.au

Tom,

I also have a Mk1 and have not had any noticable problems with water coming back up through the cockpit drains.

What sort of sea state were you in? Do you have a timber (etc) grate on the cockpit floor?

I will measure mine next time I go out, proberably this Sunday, for you.

Have you checked to see if they are not blocked with oysters etc? I do not have bungs in mine and I am sure they are bigger than 12mm. Have you checked that they come out at the same location on the centre line of the hull and the floor openings are located at the sides of the cockpit? Mine appear to be made out of very strong (read Thick walls) PVC pipe that has been fiberglassed in.

Thanks for that Phillip

On this boat there are two holes in the stern at deck level in the corners of the aft cockpit. In the marina no water comes in but underway in calm conditions the water level is slightly above the downwind hole.

From your description you have drains in the floor of the cockpit with pipes running a short distance to openings in the middle of the stern; this sounds like a better way...

Is this right?

Tom,

The idea is that the pipes should cross over to the other side of the vessel to discharge.

If yours if different, your Mk1 may have been home completed.

I will get some photos of mine and send direct to you.
